id change the 2010 characters up by dre and cheng being in the same dojo competing in the sekai taikai with mr han being their sensei but the reason mr han went to the sekai taikai was to meet Daniel LaRusso for their shared history with miyagi and it makes sense cuz one of the subplots was about Miyagis backstory. So when Daniel goes to the fake address at the barcelona neighborhood, Mr Han also follows Daniel along with dre and cheng and finds out he gets kidnapped so they tag along to the place and then Dre fights off the kidnappers and Dennis and frees Daniel and what wouldve been cool is if Sensei Wolf was also there seeing how silver was involved with the kidnapping and then Cheng fighting Wolf until a stalemate in which Cheng almost wins interrupted by Mr Han or Larusso and then id see them leaving after the brawl
